Current factors limiting and contributing to extending the duration of egg production in chickens

Abstract

Extending the life of laying hens seems to be the most relevant and logical approach to more efficient use of resources in industrial poultry farming. To achieve this goal, a multifactorial approach is required and, first of all, maintaining the physiological characteristics of the reproductive system of chickens, which is responsible for the laying of eggs by hens.Forced molting in industrial poultry farming using chemical, mechanical, hormonal, stress-inducing and other non-natural methods is not attractive from the point of view of the welfare and protection of biodiversity of the animal world.
